Definition

for a sinusoidal current, described by $i = \hat{I} e^{j (ω t - φ)}$ , complex quantity $\underset{̲}{I} = \hat{I} e^{j φ}$ ,

where $\hat{I}$ is amplitude, $ω$ is angular frequency (ISO 80000-3: Space and time), $t$ is time (ISO 80000-3: Space and time), $φ$ is the phase angle (ISO 80000-3: Space and time), and $j$ is the imaginary unit (ISO 80000-2: Mathematics).
